BPLT

Depending on how conditionally compiled, the program will either us PLPLOT or GNUPLOT libraries. The command line arguments are:

   bplt  infile idev iorient itype 1tr Ltr tmin tmax istyl amp percnt xaxis yaxis 
 
     infile   =  input file name
     idev     =  output device  
             0=    xwin/wxt  (Linux/MS Windows) 
             1=    Post Script               
             2=    xfig                      
             3=    jpeg                      
             4=    PDF                       
     iorient  =  orientation  
             0=    landscape 
             1=    portrait 
     itype    =  select non-time axis type       
             0=    trace number
             1=    offset      
             2=    geophone z-coord  
             3=    geophone x-coord  
             4=    geophone y-coord  
             5=    shot z-coord      
             6=    shot x-coord      
             7=    shot y-coord      
     1tr      =  first trace to plot 
     Ltr      =  last trace to plot 
     tmin     =  minimum time to plot 
     tmax     =  maximum time to plot
     istyl    =  style of plot
             0=    wiggle plot  
             1=   black/white variable area
             2=   black/grey variable area
     amp      =  amplitude for 1 trace deflection
     percnt   =  percent overplot 100= 1 trace  
     xaxis    =  length of x-axis (non-time) in inches
     yaxis    =  length of y-axis (time) in inches
     (if xaxis and yaxis absent, 6.0 by 4.0 inches

For example, bplt c008.seg 4 0 1 1 100 0 0.6 1 2.E+4 200 7.0 3.0
